ITEM DESCRIPTION
15. RF OUT Connector
Provides the attenuated Signal
Generator output to UUT. The
connected UUT should provide a
50
Ω termination to the RF OUT
Connector.
NOTE: The RF OUT Connector is
diode protected against an
accidentally keyed COM
Transmitter.
16. COM XMTR IN Connector
CAUTION: MAXIMUM INPUT
SHOULD STAY WITHIN
LIMITS DEFINED IN
1-3-1, TABLE 2, INPUT
POWER VERSUS TIME
LIMITS.
Provides an input to the MONITOR
Meter. Allows for power and
frequency measurements when
connected to a COM Transmitter using
a 50
Ω cable.
When the MONITOR METER
FUNCTION Switch is set to 10W or
100W, the MONITOR METER
indicates COM Transmitter power,
either peak (AVG/PEAK LOC XMTR
ON Switch set to PEAK LOC) or
average (AVG/PEAK LOC XMTR ON
Switch set to AVG). The Test Set
connects an internal 25 dB attenuator
in series with the power monitor
circuit.
When the COUNTER MODE Switch is
set to HZ, KHZ, KHZ or MHZ, the
DIGITAL Display indicates COM
Transmitter frequency.
ITEM DESCRIPTION
17. AVG/PEAK LOC XMTR ON Switch
Selects power meter function
displayed on MONITOR Meter when
MONITOR METER FUNCTION Switch
is set to 10W or 100W:
● PEAK sets the MONITOR Meter to
display peak power amplitude of a
COM Transmitter with modulation
applied. PEAK also provides
Localizer Transmitter output
simultaneously with the Glide
Slope signal when the
FREQUENCY MODE Switch is set
to G/S FIXED (for checking
Autopilots or Course Computers).
● AVG sets the MONITOR Meter for
displaying the average RF power
of a COM Transmitter and
disregards power changes due to
proper modulation.
